When I try to post one of my posts to Facebook I get the following error message: Social failed to broadcast the blog post "Help start a College Fund for your child. Enter their picture in a Baby Photo Contest and win cash." to one or more of your Social accounts.
Facebook: (Error validating access token: Session has expired at unix time 1372872298. The current unix time is 1373077961.)
Social was not successful in broadcasting this post (perhaps the service is down?), please try broadcasting again. If you receive this message repeatedly, you can try the support forums.
Looking for some help on this? It has been working fine and I have not changed a thing?
